Let the price of a notebook = X.
Multiply the cost of a notebook by the quantity, so you get 3x.
Add that to the price of a calculator to get the total spent:
60.54 = 45.87 + 3x
Now solve for x:
Subtract the cost of the calculator from both sides:
3x = 14.67
Divide both sides by 3:
x = 14.67 / 3
x = 4.89
A notebook cost $4.89
